ADJUSTABLE PARING AND SLICINGKNIFE Filed Aug. 4, 1953 Patented Aug. 281934 .UN-ITED STA PATENT OFFICE 2 Claims.

This invention relates to an adjustable paring and slicing knife, thegeneral object of the invention being to provide a longitudinallyextending opening in the rear part of .the blade of the knife,

: with means for supporting a razor blade or other blade in an inclinedposition on the main blade with its beveled edge passing through theopening.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claims.

In describingthe invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is a side View of the improved knife.

Figure 2 is a similar view with the guard or clamp removed.

Figure 3 is a similar view with both the blade and clamp removed.

Figure 4 is a section on line 44 of Figure 1.

Figure 5 is a view of the clamp or guard.

In this drawing, the numeral 1 indicates the handle of the knife and thenumeral 2 the blade thereof, which is preferably of the shape shown withits beveled edge substantially straight, as shown at 3. The majorportion of the inner part of the blade is of substantially rectangularshape, as shown at 4, with one edge extending beyond the beveled edge 3and its other edge extends upwardly and forwardly, as shown at 5. Aplate-like member 6 has its upper edge connected to the up- ,7 per edgeof this part 5 and its lower edge is connected to the part 4 at theupper edge of an elongated opening or slot 7 formed in said part, thisupper edge or wall of the opening being beveled to conform to theinclined upper or outer face of the ,40 plate member 6. The ends of themember 6 are turned up slightly, as shown at 8, at the lower portion ofsaid member and each end is formed with a projection 9 which is spacedfrom the turned-up part 8. These parts are adapted to receive thenotched end of a safety razor blade 10, as shown in Figure 2, thenotches of which are shown at 11. The cutting edge of the blade willextend slightly through the opening 7, as shown in Figure 4, and theclamping plate 12 holds the blade in position and has its major partfitting over the blade, with its curved upper edge 13 fitting over theupper edges of the parts 5 and 6 and said curved edge has a springtongue 14 depending therefrom which passes through a slot 15 formed atthe junction of the members 5 and 6, this slot being of less length thanthe length of these two parts. The member 12 is of resilient material sothat when in place, it will press the blade upon the member 6 and thushold it in place which the notches 11 of the blade engaging the parts 9when the blade is to project but a slight extent into the opening 7, butwhen the blade is to project a considerable extent, the notches willengage the parts 8. Thus the blade can be adjusted in position and themember 10 will hold it in place.

Slits 16 are formed in the ends of the part 4 for receiving the endparts of the blade when the blade is in place.

Thus I have provided simple means whereby a safety razor blade or thelike can be used on the blade of a knife for paring purposes when theblade is in its upper position, as shown in Figure 2, or for slicingpurposes, when the blade is in a lowered position. The cutting edge 3 ofthe blade 2 can be used in the ordinary manner.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims.

What is claimed is:--

1. A device of the class described comprising a blade, a handle, saidblade having an enlarged portion adjacent the handle having alongitudinally extending slot therein, the lower wall of the slot beingslightly spaced fro-m and paralleling the lower edge of the enlargedportion, the rear edge of the enlarged part extending upwardly andforwardly, a diagonally arranged plate-like member having one edgeconnected to the upper edge of said upwardly and forwardly extendingportion and its other edge connected to the enlarged part at the upperedge or wall of the slot, the junction of the upper edge of theplate-like member with the upper edge of the upwardly and forwardlyextending portion forming a rounded enlargement and the upper portion ofsaid upwardly and forwardly extending part having a longitudinallyextending slot therein, a safety razor blade, resting on the outer faceof the platelike member, and a clamping member fitting over the bladeand having a curved upper edge fitting over the rounded enlargement andprovided with a tongue for fitting in the slot in the upper portion ofthe upwardly and forwardly extending part.

2. A device of the class described comprising a blade, a handle, saidblade having an enlarged portion adjacent the handle having alongitudinally extending slot therein, the lower wall of the slot beingslightly spaced from and paralleling the lower edge of the enlargedportion, the rear edge of the enlarged part extending upwardly andforwardly, a diagonally arranged plate-like member having one edgeconnected to the upper edge of said upwardly and forwardly extendingportion and its other edge connected to the enlarged part at the upperedge or wall of the slot, the junction of the upper edge of theplate-like member with the upper edge of the upwardly and forwardlyextending portion ferming a rounded enlargement and the upper portion ofsaid upwardly and forwardly extending part having a longitudinallyextending slot therein, a safety razor blade resting on the outer faceof the plate-like member, a clamping member fitting over the blade andhaving a curved upper edge fitting over the rounded enlargement andprovided with a tongue for fitting in the slot in the upper portion ofthe upwardly and forwardly extending Dart, a pair of spaced projectionsat each end of the plate-like member and the razor blade having a notchin each end for engaging either one of said projections, whereby therazor blade can be adjusted on the plate-like member.
